This invention has reference primarily to a humidifier, medicator and deodorizer, but it is to be understood that the device may be adapted for many other uses wherein vapors are carried into the air.

An important object of the invention is to provide a device of this character wherein the heat is supplied electrically, thereby eliminating obnoxious fumes being carried into the air which is being treated by lthe device.

A further object of the invention is the provision of means to support the wick of the device in an elevated position and in such a manner that the moisture with which the wick is saturated cannot find its way into the heating chamber to short circuit the electric energy passing into the heater of the device.

With the foregoing and other objectsin View which will appear as the description proceeds, the invention resides ,in the combination and arrangement of parts and in the details of construction hereinafter described and claimed,- it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure -1 is a perspective view of a device constructed in accordance with the invention.

Figure 2 is a vertical sectional view through the device.

Figure 3 is a plan view thereof. 4

Figure 4 is a bottom plan view of the wick supporting frame.

Referring to the drawings in detail, the device includes a base 5 that provides a support for the lamp socket 6 that is secured to the flanges 7 of the base.

Forming a part of the base is an upstanding curved flange 8 formed with threaded openings to accommodate the screws 9 that secure the liquid container to the base. This liquid container is formed of an outer section 10 45 and an inner section 11, the sections' 10 and 11 being spaced apart to provide a water compartment in which the water or liquid under treatment may be placed. l

The inner and outer sections 10 and 11 of the liquid container are secured together at their bases, by means of an expansible cement 12 which insures a fluid tight connection between the inner and outer sections, but at the same time permits of expansion and contraction of the container at its point of contact with the supporting base, without danger of breaking the seal. To further insure against breakage by expansion under the heat of the heating element, an elastic ring 13 lis positioned on the lower curved end of the 4 outer section of the container for contact with the screws 9.

Positioned on the inner section of the container is a wick supporting frame including the supporting ring 14 which is in the form 65 of a band stamped in such a way that tongues 15 are provided, the tongues extending inwardly to provide a support for the supporting frame.

The wick supporting frame is substantially dome-shaped and embodies curved members 16 formed of sheet metal having their ends secured to the ring 14, the members 16 crossing each other at points directly over the upper end -of the electric lamp 17 which is 75 positioned in the lamp socket, and which supplies the heat for heating the wick and causing a vapor to arise therefrom.

In order that the heat from the lamp 17 may pass upwardly, openings 18 are provided, 80 which openings may be formed by stamping the sheet metal of which the members 16 are constructed. From the foregoing it will be obvious that the wick supporting frame is of such a construction that it will extend beyond the outer surface of the inner section of the liquid container and direct any liquid which may collect thereon, downwardly along the outer surface of the inner section.

Forming an important part of the invention is a cover or wick 19 which isconstructed in such a way that it will closely lit over the wick supporting frame in dome-like formation, the lower edge of the wick extending to a point adjacent to the bottom of the liquid container which in operation is filled with the liquid to be used with the device.

In order that the wick and liquid contained in the device will be guarded against germs and other foreign matter, a removable cover 20 is provided and is so constructed that it may be readily and easily lpositioned or removed.

In the use of the device the liquid container is filled with liquid and the cover 20 removed. The electric current'i'or lighting the lamp 17 is turned on and the heat from `the lamp will heat the Wick which is saturated with the liquid placed in the liquid container. When the temperature reaches a certain degree, it is obvious that vapors will be thrown 0f from the Wick, which vapors humidify the air and if the liquid is treated with medicine, it is obvious that the air will be medicated.

While I have shown and described the device for use as a humidiliermedicator, or deodorizer, it is to be understood that the device is adapted for many other uses of'a similar character Without departing from the spirit of the invention. 1

I claim:

l. A humidifier including a base, a body portion mounted on the base and including an inner tubular member having an open upper end, a frame positioned over the open upper end of the inner tubular member, said frame embodying a ring member, laterally extended members formed on the ring member and resting on the upper end of the inner tubular member to,support the frame, curved in the body portion, and means for directing heat to the wick to vaporize the liquid thereon.

In testimony that I claim the foregoing as my own, I have hereto aixed my signature.
